Abstract (en)
[origin: US2013322278A1] A method and an apparatus for an interference measurement method of a terminal in a mobile communication system is provided. The method includes measuring a signal component based on at least one Channel Status Information-Reference Signal (CSI-RS) allocated by a base station, measuring an interference component based on at least one Interference Measurement Resource (IMR) allocated by a base station, receiving a feedback combination configuration of the signal component and the interference component, generating feedback information including at least one of at least one Channel Quality Indicator (CQI), at least one Rank Indicator (RI), and at least one Precoding Matrix Indicator (PMI), and transmitting the feedback information to the base station.
